First off, I found a bomb stuck place on B balc, if you throw the bomb through the flash hole it will get stuck about half the time. (obv this wont happen by people who are just playing, but there are ♥♥♥♥♥ at low level play, would love to get it fixed) https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=605182868

Second, There is a little over hang on the CT sniper window that you can break a vent to get into. You can also jump into the window leaving the vent unbroken. (the jump is pretty tight but it is doable with a bit of practice, and you would give a pretty large advantage to T's who learn it)

Third, There is a moped that I guess is used to jump up on the left side of mid for people to change routs. I personaly dont like people being able to get back after making the choice to go a direction, but eather way you need to remove another one of the window sill things above it if you dont its pretty easy to bonk on.

This one is not so much a bug but an annoyance, in the lower tunnels going into B site there are some metal plates on one of the paths that make a metal sound, this is all fine and good, but they dont go all the way so you run on some gravel that also make some metal sounds (this is the part that bugs me :P)

I'm not a pro, I am a casual player who dips into comp from time to time. But I thought I would put some perspective from a lower end player, hope you found it useful.
